You could always use one of those Behringer BCR controllers, my friend uses it with his Alpha Juno keyboard and it works pretty well from memory. I keep toying with getting one for mine but I don't use the aJuno that much, can't say I'm it's biggest fan... £70 synth that filled a gap when I needed it

I've made a virtual PG300 for Logics Environment, it's exactly the kind of thing you're after if you want to tweak your Alpha Juno & use Logic.
